The book is considered a guideline for systemic personnel development in controlling of nationally and internationally active companies on the basis of a targeted development of competencies. In particular, the challenges posed by digitalization and globalization are considered and substantiated with the help of empirical studies. Employees and managers in controlling as well as HR managers in companies gain a deeper understanding of the necessity and the components of systematic personnel development. The goals are the formation of high-performance teams in controlling as well as the identification of personal career paths on the way to top management tasks as CFO. The focus of the personnel development model is on the transfer of the competence-oriented development approach, which, in addition to the traditionally considered technical and methodological competencies, also takes into account social and personal competencies as well as additional digital and intercultural competencies. The book is rounded off by a survey of the current situation, the definition of a target situation to be aimed at, the discussion of suitable further training measures and the monitoring of the level of competency achieved, and illustrates concrete career concepts.
